Heat Treatments of W6Mo5Cr4V2Si High Speed Steel

Abstract:

In this study, we conducted heat treatments on W6Mo5Cr4V2Si steel using different annealing, quenching, and tempering processes. Meanwhile, the microstructure and hardness performance of this steel are analyzed. The results showed that, in the annealing temperature range of 790°C-870°C, the higher the annealing temperature was, the better the annealing effect that W6Mo5Cr4V2Si steel presented; W6Mo5Cr4V2Si steel exhibited the lowest annealing hardness of 22.6 HRC after annealing at 870°Cfor 2 h; In the condition of annealing at 830°C for 3 h, quenching at 1200 °C around, and tempering temperature range of 400 °C-700 °C, W6Mo5Cr4V2Si steel showed the highest hardness at tempering of 560 °C around, which is about 66.7 HRC. The tempering structure of this steel was mainly composed by needle or strip-typed martensite, a small amount of residual austenite, and carbide particles.
